Well said, it is annoying to see people trash each other over and over again with the dreaded "mark" insult, when in reality, every single one of us is a mark. We all watch wrestling, presumably we all enjoy wrestling, so by definition that makes us all "marks".
Here's one that drives me up the wall: underrated. Every time I come onto this site, almost without fail, I'll see comments extolling the abilities of Matt Hardy and how "underrated" he is. He's not underrated at all. Matt Hardy is a decent wrestler that has a fun character, but he's woefully out of shape and few casual fans would take him seriously as a main event star. I like Matt, but the guy is all flab, and when you match that up against guys like Randy Orton, John Cena or Sheamus, it is a pretty wide separation. Yet we all seem to have deemed Matt "underrated".
I think that the reason for all of the misusage of wrestling terms is due to the "smarks". I'm speaking of the so-called fans who dilute this site with countless spoilers and "insider knowledge", sounding as if they're right in the WWE creative meetings, and who claim to know absolutely everything about the wrestling business. Whenever anything happens, regardless of how surprising it is, the smarks will always tell you about how they saw it coming, about how it wasn't that great and about how "they should have pushed _____" instead. They all seem to think that they know what is best for the wrestling business better then Vince McMahon does, but they also always seem to have a stunning lack of business sense. They'll tell you over and over again about how boring and predictable the WWE has become, and about how it "isn't like the Attitude Era anymore", yet they'll continue to watch, despite their frequent claims to the contrary.
Okay, my rant aside, it is these people, who love to tell you how smart they are and are just way to high on themselves, that have polluted the internet wrestling sites with previously normal terms like "mark" and "underrated". Because those are terms used by those working in the wrestling business to describe the fans in some way, the smarks jump on them, because of course they aren't regular fans, they're geniuses, and use them in vain attempts to make themselves sound smarter then the normal fan.
This in turn leads to new fans who come to sites like Yahoo Answers for wrestling discussion to see this misuse of terms and then simply think that that is what those words mean. They see the idiotic posts complaining about how predictable the WWE is and about how the champion of the day "doesn't deserve it" or "isn't ready" and as a result new fans, who just don't know any better, begin to think that way themselves. After all, they don't want other people to think that they're, gasp!, marks, so they start acting like the "smarks" themselves. It's a vicious cycle.
BQ: Don't worry, it'll die out before long. This is exactly what things would have been like during the old WWF/WCW days. You're right, it is pointless, because in today's world, with the internet and PVR, you can just watch both programs (RAW and Impact), you don't even really need to "choose" on or the other anymore. Still, regardless of how juvenile it becomes at times, it is nice to see people passionate about wrestling again.
BQ2: I like them both a lot, but I give the slight edge to Christian. He's been through the wars in pretty much all situations, and he took on all comers as the ECW Champion. Morrison would use a number of high risk moves right off the bat, but Christian, the wily veteran, would dip and dodge him, all the while getting in his own quick moves. I hope it happens, they'd have a fantastic match.
